CustomizaitonSpec Clone_VM

克隆虚拟机可以加上CustomizationSpec来自动配置好：IP地址、DNS、Domain等信息

1、可以利用PyVmimo中的vim模块在python中完全自定义CustomizationSpec（比较复杂）

2、可以首先在vSphere Web Client中创建好一个CustomizationSpec，然后在python中去完善动态的信息（比较简单）

配置示例：

完善IP地址信息

guest_customization_spec = self.content.customizationSpecManager.GetCustomizationSpec(name=customization_spec_name)
        guest_customization_spec.spec.nicSettingMap[0].adapter.ip = vim.vm.customization.FixedIp()
        guest_customization_spec.spec.nicSettingMap[0].adapter.ip.ipAddress = "1.1.1.1"
        guest_customization_spec.spec.nicSettingMap[0].adapter.subnetMask = "255.255.255.0"
        guest_customization_spec.spec.nicSettingMap[0].adapter.gateway = ["1.1.1.254"]

完成克隆示例
